Satoshi would weep after seeing centralized shitcoins like Ethereum and Cardano with massive premines and fundamental flaws in their protocols that at the same time are being sold at high prices while they have no usage whatsoever in the real world. 
Centralized doesn't always mean bad. Bitcoin has many flaws as well. But it is still enjoying the highest popularity just for being the pioneer of the cryptocurrency market. Bitcoin transactions are slow. it doesn't have smart contract functionality. The block size is small and that's why we are seeing the requirement of having Segwit and LN sorts of addons. To be honest, no cryptocurrency is flawless. All big cryptos have their own strengths and weaknesses. Just because some cryptos are somewhat centralized, doesn't mean they are worthless. Keeping our minds open will only pave way for more innovation in crypto market and that's good in long run!
